Hi,
When we are making thousands of requests to Ixnetwork rest port from ixn_client_python, it rejects the request sometimes(very rarely, once in thousands). This give an connection refused error at socket interface and disrupts the automation scripts. We can try catch in our scripts or may try with some sleep, but that will not be the best possible solution.

Can we put a try catch block in IxnHttp.py line 188, and retry for a few times before discarding the request?
Or there will be any collateral if we do that.

Hi,
We are testing the usability of ixnetwork_client_python, with headless ixnetwork centos based rest api.
While testing with the simplest sample (ixnetwork/samples/sessions/create_new_session.py) we found this error -

Build -

ixnetwork-rest==0.55a57
ixnetwork headless server (spyder) -8.50EA

P.S -> The session is getting successfully created.

• Build used:

Ixnetwork client: 8.40 EA

• Problem:

While performing post operation for some multivalue patterns - repeatableRandomRange, repeatableRandom.

Ixnetwork returns error.

• Example:

request type: POST
URL: /api/v1/sessions/<session_id>/ixnetwork/multivalue/<id>/random
response:

{
  "links": [
    {
      "rel": "self",
      "method": "GET",
      "href": "/api/v1/sessions/<session_id>/ixnetwork/multivalue/<id>/random"
    }
  ]
}

But for
request type: POST
URL: /api/v1/sessions/<session_id>/ixnetwork/multivalue/<id>/repeatableRandomRange
response:

{
  "method": "POST",
  "pathAndQuery": "/api/v1/sessions/<session_id>/ixnetwork/multivalue/<id>/repeatableRandomRange",
  "errors": [
    {
      "code": 10000,
      "detail": "One of the identified items was in an invalid format."
    }
  ]
}

Hi @ajbalogh ,
Trying to export a config in ixncfg format rather than the default json version.
This piece of code is throwing error -
Are we using in the correct way? Or is it a bug?

from ixnetwork import IxnHttp, IxnConfigManagement
ixnhttp = IxnHttp(host, rest_port=rest_port)
ixnhttp.auth('admin', 'admin')
ixnhttp.create_session()
# made a configuration
# now trying to export in ixncfg
config_mgmt = IxnConfigManagement(ixnhttp)
xpaths = [
			'/vport/descendant-or-self::*',
			'/topology/descendant-or-self::*',
			'/traffic/descendant-or-self::*'
		]
config_mgmt.export_config(xpaths=xpaths, local_filename=converted_filename,export_format = 'ixncfg')

Hi,
We use the delete method of IxnObject class,
which used to work perfectly in IxNetwork 8.40EA but now we are moving to IxNetwork 8.50EA and it is not working.

The following snippet should create an IxnObject instance and delete it.

w_topology = ixnhttp.root.create_child('topology')
w_topology.delete()

This is the traceback we are getting for 8.50EA
Exception: 405 Method Not Allowed {"Message":"The requested resource does not support http method 'DELETE'."}

Can you please look into it?

Ixn...Emulation classes should offer the functionality to find a child emulation host using a parent host

find a specific ethernet emulation using a virtual port name
eth = IxnEthernetEmulation(ixnhttp).find(vport_name='PE2-6/8')

find the igmp host emulation using the eth emulation host
igmp = IxnIgmpHostEmulation(ixnhtt).find(eth)

Hi,

I'm testing ixnetwork_client_python with IxNetwork Connection Manager 8.40.1124.8 in GUI mode.
I was able to use the API to create a few sessions. However, when I tried to connect to existing sessions, I got a 404 error.

It turned out the Connection Manager does not like GET request /api/v1/sessions?links=true. If I manually issue _send_recv('GET', '/api/v1/sessions') then I could query a list of sessions in the Connection manager.

What is the best way to address this issue?
